The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"hd-73267-b","name":"HD 73267 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":164.41314691236636,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":129.0735123,"dec_deg":-34.4594469,"epoch_ra_deg":129.337043,"epoch_dec_deg":-34.552203,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 73267","semi_major_axis_km":333453653.7903,"periapsis_km":null,"mass_kg":7.892402085812332e+27,"mass_msun":0.0039692,"constellation":"Pyxis","discovered":"2008","featured":false,"url":"https://spacecatalog.org/object/hd-73267-b","radius_km":82915.3,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 73267","host_v_mag":8.9,"eccentricity":0.261,"uncertainties":{"mass_kg":[9.851266672558214e+26,1.2926228524522432e+27],"distance_ly":[0.23678953022235572,0.23776799935550597],"eccentricity":[0.004,0.004],"host_mass_solar":[0.119,0.119],"inclination_deg":[7.66,7.614],"host_radius_solar":[0.033,0.033],"host_temperature_k":[10,10],"semi_major_axis_km":[14959787.07,13613406.233699998],"orbital_period_days":[0.60358,0.50697],"argument_of_periastron_deg":[0.823,0.836]},"host_mass_solar":0.93,"inclination_deg":130.843,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":0.909,"planets_in_system":2,"discovery_facility":"La Silla Observatory","host_spectral_type":"K0 V","host_temperature_k":5387,"orbital_period_days":1257.99159,"periastron_epoch_bjd":2451822.849,"equilibrium_temperature_k":165.89,"argument_of_periastron_deg":228.102},"designations":[{"catalog":"Exoplanet","designation":"HD 73267 b"}],"source":{"id":"exoplanet_archive","name":"NASA Exoplanet Archive (Planetary Systems Composite Parameters)","url":"https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars","license":"Public domain (NASA)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
